I have been trying to research this disease, but haven't found a "simple" explanation. I have been informed of the presence of white line disease in my donkeys lives. I don't whether they have or had it, as I don't know that much about white line disease. My main questions are: 1. What is white line disease? and 2. How will it effect my donkeys lives as miniature trail donkeys and as brood donkeys? any other information is appreciated.
